PROCESS OF PRODUCING PHOTOGRAPHIC MOUNTS.

SPECIFICATION formingpart of Letters Patent No. 662,579, dated November 27, 1900..

Application filed May 8, 1900. Serial No. 15,886. (No specimens.)

T0 wZZ whom it may concern.-

Be it known that I, PAUL J. STUPARICH, a citizen of the United States,residing in the city and county of San Francisco, State of California, have invented an Improvement in Processes of Producing Photographic Mounts; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a process of producing photographic mounts; and it consists of the steps constituting the process hereinafter described and claimed.

Figure 1 is a longitudinal elevation of a dis- Fig. 2 is a view of a plate in the chase, showing a shaded surface. Fig. 3 is a view of a plate, showing a depressed outline around the same.

It has been the practice to variously color or shade the full surfaces of cards or sheets of paper which are afterward used for mounting photographs, this shading being done by the use of Wash tints laid on by hand in the usual manner of such shading.

It is the object of my invention to produce variously-shaded card mounts for photographs by proper blending of suitable inks upon the printing-plate and so mounting said plate and the cards which are to be printed as to properly apply the shade at a single impression.

In carrying out my invention I employ a press of well-known construction having inkfountains located side by side and containing inks of different shades or colors. u The distribution-roller, which passes over these fountains during the movements of the press, has a certain amount of end reciprocation, so that as it takes ink from the fountains it blends the lighter and darker shades, thus producing a gradual darkening of the shade from one side to the other, and this is then applied to the plate by which the impression is to be made.

The printing-plate A has the center cut out, as shown at 2, and it may have surrounding lines or ornamental configuration exterior to the cut-out portion, as shown at 3. This plate may be fixed in the chase, so as to receive the shade tint from the roller in any desired manner. I have here shown it as being fixed 5o diagonally in the chase, so that the shade will extend from one corner to the other with a gradually-deepening tint. The cards are placed upon the bed so as to coincide with the position of the plate, and they are thus printed at one impression with the desired shade upon them.

If it is desirable to form a depressed outline around the card, as at 4, or to form what is known as the pebbled surface upon the exterior parts, it is done by a second suitablyformed die and a second impression. The card when completed thus has a white unprinted center and a peripheral border, which is shaded or tinted, as before described. The tint may be placed in any desired relation with the outline of the card by the placing of the printing-plate and the card with relation to the fountain. The white imprinted field is of considerable size, and when the designed print is mounted upon one of these cards there remains outside of it a white or unprinted border, which gives a heightened effect of contrast between the shaded mount and the photograph. The essential object in preserving the white field is to produce this contrasting border, which latter is varied in width according to the taste of the artist and the size of the print; but it should be preserved in all cases to obtain the desired results.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The process of producing photographic mounts consisting in removing the center from the printing-plate and applying a shaded ink to the remaining portion of the plate to form a deepening tint from one side or angle to the other and bounding an uncolored center, and finally impressing the plate upon a card placed to receive the impression.

In witness whereof I have hereunto set my hand.

PAUL J. STUPARICH.
